MIC2033-55AYM6-TR

Overview

The MIC2033-55AYM6-TR is a high-side power distribution switch manufactured by Microchip Technology. It operates within an input voltage range of 2.5V to 5.5V and features a typical on-resistance of 75mΩ at 5V. The device provides fixed current limit options including 0.5A, 0.8A, 1A, and 1.2A, with ±5% accuracy. It incorporates thermal shutdown protection and undervoltage lockout (UVLO). The component utilizes a 6-pin SOT-23 package and supports logic-controlled enable inputs for active-high or active-low operation.

Feature Summary

• High-side MOSFET power distribution switch design
• Internal current limiting with thermal shutdown protection
• Open drain fault status output flag with delay
• Capacitor-adjustable soft-start circuit

Applications

• Power distribution in portable electronic devices
• Hot insertion applications requiring inrush current control
• System reliability enhancement in embedded circuits
• Protection of downstream loads from overcurrent conditions

Procurement Notes

Verify the specific current limit rating associated with the suffix '55' against official datasheets, as standard variants typically use numeric codes like 05, 08, 10, or 12. Confirm package type and RoHS compliance status directly with the manufacturer before ordering. Ensure the enable logic polarity matches the system requirements.

Selection Notes

Select this component for applications requiring precise current limiting and system protection. Consider the soft-start capability for capacitive loads. Verify that the operating voltage range aligns with the system supply. Check pin compatibility with existing designs if replacing older models like the MIC2005 series.

Part Context

This part belongs to the MIC2033 family of high-side power switches. These devices are designed to improve system reliability by protecting loads and preventing damage during fault conditions. The family offers various current limit options and packaging choices to suit different application needs.

Replacement Considerations

The MIC2033 is pin-compatible with the MIC2005 series. When substituting, verify that the replacement device meets the required current limit accuracy and voltage specifications.
